DUMPING-WAGON.

SPECIFICATION forming part ofLeaers Patent No. 283,262, dated August 14, Issa To all whom, it may concern.-

Beit known that we, WILLIAM LEONHARDT and JOHN H. LEONHARDT, of Baltimore county, Maryland, have invented ccrtainnew and useful Improvements in Dumping Oartsor /Vag with the body raised above the wheels and turned ready to be dumped at right angles thereto. Figs. 4 and 5 are detail views, Fig. 4 being a partial section showing'the body, the` uprights, and raising-chains; and Fig. 5, a fragmentary View, showing means Awhich we sometimes use in turning the body and its supporting-fra1ne or turn-table. I

Like letters of reference niark the same parts in all the figures.

Our invention relates to that class of Wag ons and carts in whichthe body is raised and dumped, allowing the contents to run out through a chute, and which are generallyu-sed to pass coal directly into buildings withoutV the necessity of dumping on the sidewalk and then shoveling it in, and has for its object to furnish an improved cart or wagon, the body of which may be raised above the wheels, turned at an angle thereto, and emptied, the object beingto permit ofthe dumping through the `chute in narrow streets and alleys, and between car-tracks and the sidewalk, in an expeditious manner 5 and to this end our invention consists of certain improved constructions, arrangements, and combinations of devices, which will be first fully described hereinafter, and then pointed out in the claims.

Referring to the drawings by letter, A Aare the wheels, B the axle, and G C the shafts of a cart, which parts `have no peculiarity inn their construction.

The shafts are joined by cross-pieces D D, which inakewith the shafts a rigid framework, upon which rests a turn-table arranged to rotate on a central point, e, and moving on a 'fifth-wheel, F. This turn-table may bero-- tated by hand or by anysuitable mechanism-4 as, for instance, by meansof a rack and pin- V'ipplication filed June 15, 1893. (No model.)

ion and crank, as shown-in Fig. 5, and may slide around as does the ordinary Yfifth-wheel of a wagon; or, if necessary, anti-friction rolls may be interposed to facilitate themovement.

rlhe turntable is com p osedof a'square frame whose sides are equal in length with the width ofthe shaftframe, the four sides being marked,

respectively, f f and j" f. A central cross- -piece, f2, isalso provi-ded, to which the pivot e, upon which the turn-table rotates, is attached. directly over the axle when the parts are in the positionshown in Figs. l and 2. `An upright, y, risesfroln each of the sides f f of the turntable, `which are properly stayed by braces g', extending'fo the sides f f.

`H is the body of the cart or wagon. It is provided with bearings for pivots j, attached\ to the ends of chains J by means of links j. These bearings are centrally placed longitudinally of the body, and serve as the points of rlhis central beam or cross-piece is I suspension when the body is raised, as will be y now explained. rlhe chains J eXtendfrom the pivots upward over pulleys y, journaled in the upper ends of the uprights g, and from `thence downward on the outside of said uprights to drums or shafts K. These drums are mounted at their inner ends in the uprights g, and their outer ends in brackets L which brackets consist of two arms, Z, secured to the sides of the uprights y, which arms extend downward and outward, and, joining together near their midlength,'form a single arm, l', which is secured to the side `bars of the turntable and contain the bearings for the outer ends of the shafts or drums K, as aforesaid. The division of the upper ends of these brackets into two arms permits of the chains passing directly down from the upper endsl of the uprights to the shafts or drums between these arms. The sh afts K carry gear-wheels 7c, which mesh with pinions m on a shaft M, which `is mounted in the frame-work of the turn-table and in bracket-bearings N N', secured to the `outside thereof. rlhe bracket N/ contains also bearings fortwo chain-wheels, P P, the former of which is on the shaft M and the latter on a short shaft, M', which is provided at its outer end with a squared portion to receive a crank for the purpose of turning it.

Ioo,

One side of each of the uprights g is provided with a ratchet, q, with upward-pointed teeth, to engage a pawl, q', pivoted to the side of the body, and being connected beyond the pivot with the upper end of a link, q2, whose lower end is connected to the arm g3 of an elbow-lever pivoted at its angle to the body, the other arm, g, extending horizontally, and is i held normally in its lowest position, to keep the pawl normally engaged with the ratchet by a spring, q?. When raised to disengage the pawl, the elbow-lever engages, by friction, with the spring q, and is held -in such position until' returned by hand.

On the side of the body, near its rear end, is a loop, R, (carrying roller o3) through which passes'a bar, R, perforated at intervals, as at r, to receive a pin to regulate the angle to which the vbody shall be dumped, said bar being pivoted at its lower end to the frame of the turn-table.

It will be observed that all tendency of the body to swing longitudinally is prevented by means of grooves s in the inside of the uprights, in which the pivots move. These grooves .may be lined or faced with metal, if desired, to prevent wear, and rollers may be attached to the body to prevent binding by reason of any giving of the uprights toward each other.

The upper portion of the uprights which carry the body may be hinged to lie down on the body, if desired, so that the vehicle may pass under any obstruction that might inter- I fere with it were this not the case, and in this construction a sli p-bolt will be used to stiffcn the uprights when raised.

The operation of our device is as follows, viz: The body being loaded and in its lowest position, and it being desired to dump it in, it is raised by turning the crank and winding the chains on the drums until the proper height is reached, the pawlV and ratchet being always in engagement and preventing a descent should the chain or any of the shafts or gear break, when the angle of the body is fixed by the reg ulating-bar and the coal or other load is allowed to run out into a chute in a manner well known. Should the position of the cart or wagon be such-as, for instance, in a narrow alley, or in a street between the cartracks and the curb-that it is impossible to dump the load in the rear, the inode of procedure will* be changed in this respect, viz: Vhen the body has been raised sufficiently high to clear the wheels, the turn-fable will be turned within the wheels, carrying with it, above the wh eels, the loaded body, until the body is at the ydesired angle, and'then the angle is fixed and the load allowedto pass out as before. It will be seen that the only part which projects beyond the wheels is the body, all the turning mechanism being entirely within them, and that all the mechanism for raising and turning is simple and strong and not liable to break or get out of order. The advantage of being able to dump at an angle need not be more than mentioned, being obvious.

Having thus fully described the construction and operation of our invention, what we claim as new, and desire to secureby Letters Patent, is f l. The combination, in a dumping-wagon, of the body, a turn-table provided with a standard on each side, raising mechanism, substantially as described, carried by said turn-table, and the main frame upon which -said turn-table is pivoted, the turn-table and raising mechanism operating entirely between the wheels, as set forth.

2. In combination with the main frame of 8o a dumping-wagon, a frame thereon and having an upright at each side, carrying a grooved wheel at its upper end, the body, a pivot journaled in each side thereof, a chain attached to each pivot and passing over the grooved wheel,

and means, substantially as described, for wind the body, and its raising mechanism, of the l pawl-and-ratchet mechanism described, for the purpose set forth.

5. The combination, with the main frame, the turn -table, the uprights and their pulleys, the body, its pivots, the chains, and their winding mechanism, of mechanism, substantially as described, attached to the turn-table and engaging with the body, whereby the angle of the body in dumping may be regulated without regard to the angle to which it is turned, as set forth.

In witness that we claim thev foregoing we have signed our names to this specification in the presence of two witnesses.
